HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 790,638, dated May 2s, 1905.

Application iiled November' 25, 1904. SerialNo. 234,267.

To all roh/0710, it may concern:

Be it known. that we, JOSEPH F. JoY and J AMES CLARK, citizens of the United States of tion between two cars,and the coupling is con-v structed whereby the same will be iieXible and can adjust itself to the movement of each car. The many other objects and advantages will be apparent from the following description, taken in connection with the drawings, and in describing the invention in detail reference will be 'had to the drawings accompanying this application, wherein like numerals of reference designate corresponding parts throughout the several views, in which- Figurel is a bottom plan View of our im# proved hosecoupling,showing two sections of hose connected together. Fig. 2 is an enlarged detail view of the iieXible jointemployed in connection with our improved hose-coupling.`

Fig. 3 4is a transverse sectional view taken on the line :n w of Fig. 2. Fig. 4 1s a detail sectional view of a sleeve which is used Yupon the y adjoining ends of the hose-sections. Fig. 5 is a detail View' of a hanger, and Fig. 6 is alongitudinal sectional View of the flexible joint of our improved hose-coupling.

The coupling employed by us is particularly adapted for use upon railway-trains for connecting cars together', whereby steam or air may be conveyed from one end of the train to the other. In connection with our improved hose-coupling we employ two hangers 1 1, which are adapted to be secured to the bottom face of the sills of railway-carsor secured in any desirable place where it is desired to lessary to describe one oi said sections.

maintain a coupling between two cars. The

hangers a-re secured-to the cars by the screws V2 2, and each hanger consists of an annular baud 3, which is lprovided with set-screws I 4.

Each section of hose is designated by the reference-numeral 5, and'as each section is identical in construction we only deem it nec- The hose 5 'upon the end of the car is adapted to be retained within the hanger 1 by the setscrews 4C. The opposite end of the hose is provided with a metallic collar 6, which is secured thereon by split bands 7 these bands being retained thereon by nuts and bolts 8.

In the end oi' the hose-section 5 which is to be joined to a section of hose carried by another'ca'rY is placed the joint member 9, this member being retained within the hose by the metallic collar 6. The joint member is provided with an annular flange 10, and the one end of the joint member is formed semispheru ical, as designated at 11. 'The joint member is provided with a bore 12, and the end ofthe bore which passes through the semispherical portion of the joint member is recessed, as indicated at 14, to receive an annular resilient washer 15.

The flange 10 is provided with recesses in its periphery, as designated at 16, and' in these recesses are secured the diametrically-opposed spring-arms 17 17, these arms extending outwardly from said iiange and have their outer ends slightly curved, as indicated at 18 18.

Pivotally connected to the lange 10 by setscrews 19 19 is a ring 2O. To the opposite sides ot' the ring are pivoted the bifurcated -arms 21 21 oi"v a sleeve 22, set-screws 23 being employed to pivotally connect said sleeve to the ring 20. The sleeve has a larger diameter than the metallic collar 6, and said sleeve is adapted to surround the collar, as clearly illustrated in'Fig. 2 of ther drawings. The bore oi' the sleeve is threaded, as indicated at 23', to receive the end of la spiral spring 24, that is adapted to surround the section of hose 5, the opposite end oi' the spring being secured adjacent to the hanger 1.

As heretofore stated, the sections of hose 5 are identical in construction, and each is adapted to carry the parts just described, and

it will be observed from Figs. 1 and 2 of the drawings that the spring-arms 17 of one joint member are adapted to engage the semispherical end of the opposing joint member'. By this means the annular resilient Washers will be retained in engagement with one another and the one hose-section placed in communication with the other. It will also be observed that each joint member is pivotally mounted within a ring, which is similarly mounted within a sleeve carried by the end of the hose, and this construction will permit of the adjoining ends of the hose-coupling adjusting themselves to a position common to that of the ends of the cars.

Set-screws may be employed for securing the sleeve 22 in one position in respect to the hose-sections 5 5 and may also be employed for retaining the end of the spiral spring 24 within said sleeve.

The spiral springs 24 are employed for protecting the sections oi' hose 5 in the diii'erent positions which they may assume.

While we have herein shown the preferred manner of constructing our improved hosecoupling, it is obvious that various changes may be made in the details of construction without departing from the general spirit and scope of the invention.

Having fully described our invention, what We claim, and desire to secure by Letters Patent, is-

l. A hose-coupling comprising two sections of hose adapted to be carried by two cars, a joint member carried by each section of hose, means for securing said joint members together, a sleeve pivotally connected to each joint member and a spring attached to each sleeve and surrounding the hose-section.

2. A hose coupling of the character described, comprising two sections of hose adapted to be connected together, a joint member carried by each section of hose, means forsecuring said joint members together, a sleeve pivotally attached to each joint member, said sleeve being formed with an internal thread, a spiral spring surrounding each hose-section and screwing into said sleeve.

3. In a device of the character described, the combination of a section of hose, a spring surrounding said section of hose, means for attaching one end of said section of hose and one end of said spring to a car, a coupling member rigidly attached to the opposite end of said section of hose and a sleeve pivotally attached to said coupling member and rigidly attached to the end of said spring.

4. In a hose-coupling for cars, the combination or' two sections of hose, means 'to attaching each section of hose, at one end, to a car, a coupling member carried by each section ol hose, a ring pivotally connected to each coupling member, a sleeve pivotally connected to each such ring and a spring` connected to each sleeve and surrounding the hose-section.

5. In a hose-coupling ior cars, the combination of a hose-section, a spring surrounding the hose-section and means Afor rigidly attaching one end of the hose-section and one end of the spring to a car, with a coupling member carried by the free end of the hose-section, a sleeve attached to the free end of the spring and a universal-joint connection between said coupling member and said sleeve.

In testimony whereof we afiix our signatures in the presence ot' two witnesses.

JOSEPH F. JOY. JAMES CLARK.
